Not stupid at all - the mini / crazy courses although covered with a smooth putting felt are all basically contoured concrete platforms

Here's one in Hastings before the felt is laid

Dave_L - if we need to factor in some extra concrete, do you normally have a rough 'rule of thumb' guide of the extra % it might need?

its called a contingency stoichkov, on a job like this you would probably have a 5 % contingency to be agreed with the client ,architect,and builder
also would probably be 2.5% retention for 6 months

when the digging starts there are all sorts of things that can crop up that could add to the cost
but if using concrete or bitmac you really need experienced concrete finishers/tarmaccers for this sort of thing
I wonder if the yanks have this sort of thing in kit form?
they love a bit of concrete

I understand the contingency idea, but whats a retention?

Is that some of the contract value withheld until a set period following completion of the work?

a retention is a percentage of the contract value withheld for a period of either 6 months or 12 months to cover any defects what may arise with the work

for example this percentage can vary from 2.5% to 5%, its what ever has been agreed with the contractor and yourselves before the work commences

What do you guys reckon about damp proof courses? One possible contractor specifies them, the others don't. I can see the sense in them, but do they do their job?

The other thing is soakaways. Again, one contractor (who has built courses before) is adament they are needed but this would involve quite a bit of extra excavtion to accomodate them. Our site is about as free-draining as you can get - It's never been known to have any standing water or flood at any time. We'd plan to have drainage holes at key points around the surrounding bricks and would sink the actual 'golf hole' nice and deep. Some water could drain out the sides into the grass but most would find its way down the main hole which, in effect, is a sort of soakaway anyway?

I take it you mean damp proof membrane as in visqueen sheeting underneath the concrete then yes I would put it in

dig a few trial holes dotted about the site 400mm x 400mm x 400mm deep and fill it with water, if it disappears in a few seconds then you should not need any surface water drainage, if it takes hours then yes you will need soak a ways for your drainage because I am sure you don't want to be handing out wellington boots to your customers just to play a round of crazy golf :;):

constructing the holes with a concrete base is not required.the modern artificial putting or lawn turf manufacturers will tell you that.the turf is porous.there is a spec for the sub-base construction to ensure it is self draining.

presumably you've putted on "felt" surfaces,with a concrete base,you see on some crazy golf courses and realised that they are crap?

the idea with the new adventure golf courses springing up is to create a fun and realistic putting experience for all the family,not just the kids. choosing the correct materials for this and speaking to contractors with experience of laying these materials is obviously key.

Hey bobbi,

I know the modern artificial turf that you mean but the type we want is the traditional felt glued onto concrete.

This is one of those artificial turf ones in Sweden:

Very nice looking (i'd love to play one), but we're still after the more 'crazy golf' type with Windmills etc!

Sorry for the bounce

We've started building now. If anyones interested, the link below has a load of photos which we're updating as we go

very nice stoichkov,there is something quintessentially British about crazy golf,although i have played them in other countries
i like the ones with tunnels where the ball disappears briefly :)

Morning.

It's coming along. Here's the hole above but now with concrete & brickwork complete

Here's an overview of the course

For you blokes it must have been routine but for me, the day of the concrete pour was equally one of the most exciting & scary days of my life!

my constructive critcism would say, wheres all the water going? too many straight lines. too much concrete materials on show. too flat. too few natural contours.

looks like you did all the research,had a picture of what the course should look like then took nothing on board and did the opposite!

did you forget that you only get one shot at these things and if its crap the punters dont come back?

Ouch! :laugh:

When we had some heavy rain around easter, the builders looked at where the water was pooling and then contoured it off gradually to take the water away. The upshot is that the course doesn't have any standing water on it during periods of rain.

There will be additional planting around the holes and we've got to add the wooden features last after the green felt has been laid.

As its in a conservation area, we were restricted in terms of height etc but we think that the design of the holes in how they play makes up for this.

I'll stick some more pictures up after it's finished..

Hey!

I remembered this place so thought i'd pop back and post a couple of pics. Cheers for the advice - it came in useful

We're still adding to the planting each year but its starting to 'mature' a bit more now

We did have to drill out a few more drainage holes in the sides as, under heavy rainfall, we do get a fair bit of standing water

If I do another, i'll pick your collective brains again!

cheers!
